In the past, I've had people ask me if I knew of any apartments in Hong Kong that would sleep 10 or 11, or some huge number like that.  They also wanted something cheap.  Regretfully, I would always have to explain to these folks, "No way, forget it."  But recently I've stumbled on to a few that offer just this thing, accomodation for many. 

Here is a 600 sq. ft. flat that the owner claims can hold 16 people or perhaps even more.  Now trust me, this is going to be crowded and not the safest or most comfortable setup going.  However, if this is what you need, have at it.  His price starts at $88 for 3 people and you keep adding $10 for each additional person.  What a deal for a large group traveling together.  Spend your money on food and shopping instead of hotel rooms!

And if you need a place for only 12 people, check this 1500 sq. ft. Causeway Bay location out.  This one looks very nice and would not be as jammed pack as the other one, yet the price is $290 per night but that is for 12 people.  There is no extra charge after 3 or anything like that.  Now I can tell from the location that this will be a very old and likely run-down building but then again who cares what the outside looks like as long as the apartment is fixed up nice and it appears to be.
